Looks like others have concluded the same thing. I think I'm going to ditch Rogers' DNS. I've had connection problems in the past, but couldn't pinpoint them since I've also been constantly changing firmware.

It's complete trash in London right now (North). ping timesa re fine, page loads not so much so I suspect you are all on the right track. It's been inconsistent all week speed wise (ping times in games from 24ms up to 400ms) but not it is outright ruined. I'll try it again in a few hours, this page took almost 5 minutes to load :O!

Yes, but for me it seems like a combination of DNS plus other issues. I was occasionally connecting to some sites (but not most) via Rogers DNS. Switching to Google seems to work better but it still slow loading pages (although at least it can now find them).

Like others have said, switching to Google DNS seems to work great. My phone data on the other hand is messed up too. Tried to call rogers and they are even having issues with their support centre. Must be getting flooded with calls!
